The Maban languages are a small family of languages which have been included in the hypothetical Nilo-Saharan language family.
Maban languages are spoken in eastern Chad, the Central African Republic and western Sudan (Darfur).
The Maban branch includes the following languages:
The languages attested in two word lists labelled "Mimi", collected by Decorse (Mimi-D) and Nachtigal (Mimi-N), have also been classified as Maban, though this has been contested. Mimi-N appears to have been remotely related to Maban proper, while Mimi-D appears to have not been Maban at all, with the similarities due to language contact with locally dominant Maba.
Blench (2021) gives the following classification:[1]
Based on morphological evidence such as tripartite number marking on nominals, Roger Blench (2021) suggests that the closest relatives of the Maban languages may be the Eastern Sudanic languages, especially the Taman languages, which form a branch within Northern Eastern Sudanic.
Maban also shares lexical similarities with the Fur languages, Saharan languages, and even Songhay languages, but generally has more lexical matches with Eastern Sudanic languages.[1] Lexical similarity may nonetheless be due to language contact, so that it constitutes less compelling evidence for genealogy than morphological similarity, for instance.
Glottolog considers Maban a small but separate language family.
Blench (2021) posits the following consonants for proto-Maban:[1]
Vowels likely were ATR pairs, with at least *a *ɛ *e *i *ɔ *o *u and possibly *ɪ *ʊ, plus length.
There were likely two register tones plus the possibility of contour tones on long vowels.
